Public Attributes
size_t	block_size
	Block size in bytes.

bool	chaining
	If true, includes a chaining mode. If false, can process only one block.

const UChar *	chaining_name
	Chaining mode name.

const void *	fixed_iv
	If not null, point to a fixed IV for that algorithm.

size_t	fixed_iv_size
	Size in bytes of the fixed IV.

size_t	max_iv_size
	Maximum initialization vector size in bytes (chaining).

size_t	max_key_size
	Maximum key size in bytes.

size_t	min_iv_size
	Minimum initialization vector size in bytes (chaining).

size_t	min_key_size
	Minimum key size in bytes.

size_t	min_message_size
	Minimum message size. Shorter data cannot be ciphered in this mode (chaining).

const UChar *	name
	Algorithm name.

bool	residue_allowed
	The chaining mode can process residue after the last multiple of the block size.

size_t	work_blocks
	Temporary work buffer size in multiples of cipher block size (chaining).

Detailed Description

Properties of a block cipher.

Constructor & Destructor Documentation

ts::BlockCipherProperties::BlockCipherProperties	(	const UChar *	name,
		size_t	block,
		size_t	min_key,
		size_t	max_key = `0`
	)

Constructor for a basic block cipher.

Parameters

[in]	name	Algorithm name.
[in]	block	Size in bytes of the daa block.
[in]	min_key	The minimum key sizes in bytes.
[in]	max_key	The maximum key sizes in bytes. If zero, same as min_key_size.

ts::BlockCipherProperties::BlockCipherProperties	(	const BlockCipherProperties &	base,
		const UChar *	name,
		bool	residue,
		size_t	min_message,
		size_t	work_blocks,
		size_t	min_iv,
		size_t	max_iv = `0`
	)

Constructor for chaining block ciphers.

Parameters

[in]	base	Properties of the base cipher.
[in]	name	Chaining mode name.
[in]	residue	The chaining mode can process residue after the last multiple of the block size.
[in]	min_message	Minimum message size. Shorter data cannot be ciphered in this mode.
[in]	work_blocks	Temporary work buffer size in multiples of cipher block size.
[in]	min_iv	Minimum initialization vector size in bytes.
[in]	max_iv	Maximum initialization vector size in bytes. If zero, same as min_iv.

ts::BlockCipherProperties::BlockCipherProperties	(	const BlockCipherProperties &	base,
		const UChar *	name,
		const void *	fixed_iv,
		size_t	fixed_iv_size
	)

Constructor which overrides a few fields.

Parameters

[in]	base	Properties of the base cipher.
[in]	name	If not null, override full algorithm name, including chaining name.
[in]	fixed_iv	If not null, point to a fixed IV for that algorithm.
[in]	fixed_iv_size	Size in bytes of the fixed IV.
